Brief Summary:
The purpose of this study is to evaluate the experimental immunotherapy agent cemiplimab-rwlc when given after completion of chemotherapy and radiation treatment and determine if it will improve progression free survival and cure rates in patients with PD-L1 positive locally advanced head and neck cancer.

Primary Outcome Measures :
  1. Progression-Free Survival (PFS) [ Time Frame: Up to 2 years ]
    Progression-Free Survival (PFS) is defined as the elapsed time from the date of starting maintenance treatment until disease progression or death (whichever occurs first). Patients who have not had an event will be censored at the date of last disease assessment documenting the patient was free of progression. Progression will be assessed using the Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1.


Secondary Outcome Measures :
  1. PFS Rate [ Time Frame: Up to 1 year ]
    PFS is defined as the elapsed time from the date of starting maintenance treatment until disease progression or death (whichever occurs first). Patients who have not had an event will be censored at the date of last disease assessment documenting the patient was free of progression. Progression will be assessed using the Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1.

  2. Overall Survival (OS) [ Time Frame: Up to 2 years ]
    Overall survival (OS) will be defined as the elapsed time from the date of starting maintenance treatment (Cycle 1 Day 1) until death. Alive patients will be censored at the date of last known to be alive.

  3. Incidence of Treatment-Related Toxicity and Adverse Events [ Time Frame: Up to 9 months ]
    Safety of the intervention will be reported as the incidence of treatment-related toxicity, including serious adverse events (SAEs) and adverse events (AEs), in study participants using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, per physician discretion.

Criteria

Inclusion Criteria:

  1. Histological diagnosis of squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx
  2. Intermediate or high-risk disease defined by the following:

    1. Squamous Cell Carcinoma of the oral cavity, larynx or hypopharynx American Joint Committee on Cancer (AJCC) 8th Stage III-IVB
    2. p16-Negative oropharynx SCC, AJCC 8th Stage III-IVB

  4. Prior therapy for advanced stage HNSCC with definitive Standard of Care (SoC) CRT Intensity Modulated Radiation Therapy (IMRT (66-70 Gy) with concurrent Cisplatin with curative intent. Patients must have received a total cumulative dose of cisplatin of ≥ 200 mg/m2 or equivalent carboplatin plus taxanes combination per investigator criteria during concurrent treatment.
  5. No clinical or radiographic evidence of progressive disease at the time of enrollment.
  6. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤ 2.
  7. Adequate bone marrow function, including:

    1. Absolute Neutrophil Count (ANC) ≥ 1,000/µL or ≥ 1.0 x 10^9/L.
    2. Platelets ≥ 75,000/µL or ≥ 100 x 10^9/L.
    3. Hemoglobin ≥ 8 g/dL (may have been transfused).
  8. Adequate renal function, as determined by an estimated creatinine clearance ≥ 30 mL/min as calculated using the Cockcroft- Gault.
  9. Adequate liver function, including:

    1. Total serum bilirubin ≤ 1.5 x upper limit of normal (ULN)
    2. Aspartate and alanine aminotransferase (AST and ALT) < 2.5 x ULN.
  10. Pregnancy test (for patients of childbearing potential) negative at screening.
  11. Male patients able to father children and female patients of childbearing potential and at risk for pregnancy must agree to use two methods of contraception (at least one of which is considered to be highly effective throughout the study and for at least 3 months after the last dose of cemiplimab-rwlc.
  12. Evidence of a signed and dated informed consent document indicating that the patient (or a legally acceptable representative, as allowed by local guideline/practice) has been informed of all pertinent aspects of the study.

Exclusion Criteria:

  1. Prior immunotherapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-Cytotoxic T lymphocyte Associated (CTLA)-4 antibody (including ipilimumab), or any other antibody or drug specifically targeting T cell co-stimulation or immune checkpoint pathways.

  9. Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA [ribonucleic acid] if anti-HCV antibody screening test positive).
  10. Pregnant female patients, breastfeeding female patients, and male patients able to father children and female patients of childbearing potential who are unwilling or unable to use 2 methods of contraception (at least one of which is considered to be highly effective) for at least 3 months after the last dose of cemiplimab-rwlc.
  11. Patients with impaired decision-making capacity.
